A 0.13-kg k g baseball moves toward home plate with a velocity v⃗i v → i = (-37 m/s m / s )x^ x ^ . After striking the bat, the ball moves vertically upward with a velocity v⃗f v → f = (28 m/s m / s )y^ y ^ .

A) Find the direction of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 msms.

B) Find the magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 msms.

C) How would your answer to part B change if the mass of the ball were doubled? (is it 1. triple in magnitude, 2. double in magnitude, or 3. impulse would not change.)

D) How would your answer to part B change if the mass of the bat were doubled instead? (is it 1. triple in magnitude, 2. double in magnitude, or 3. impulse would not change.)

A soccer ball of mass 0.31 kg is rolling with velocity <0, 0, 2.1> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.37 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you...
